My jaw dropped when you made his line visible! Haha I need one of these and one of HIM

You have answered a lot of questions for me. Your teaching style is exemplary

Timing of this video is uncanny for me! I too watched Home theatre Gurus tutorial on multi sub setup with REW & miniDSP a couple of times. Excellent tutorial but wish there was a cheat sheet version for reference. After spending about 15 hours previously on figuring how to use REW, umik1 & miniDSP & still falling short, I just spent 6 hours yesterday tweaking the system...finally success! Lessons learned (& still learning) are similar to your experience. Per Home Theater Guru’s video, I learned sub placement is critical and I moved each sub one by one to minimize the severity of the nulls. Then played them both and found through trial & error which sub required the time delay. Through placement and time alignment you get the subs as good as you possibly can get without EQ, then go into REW and use the EQ tab to achieve the target curve. Patience is paramount to this whole process but it is all worth it in the end!

Hello! Just wanted to let you know that the rise in output in the lower frequencies of the subwoofer response is due to the way our ears perceive sub bass. You need to have that rising response the lower the frequency gets for you're perception of flat response, even if it measures as a rise. So, it just the way our ears and bodies respond to lower frequencies.

Just want to say your videos are highly appreciated. Not only because they're so well done, but more because they're clean and respectful in a world full of negativity and filth. Thank you!

Youthman quote of the day "I need to go check my drawers kind of thing to make sure something didn't slip out"
🤣
That's awesome you guys were able to fine tune the subwoofer frequencies.😉👍

Just seeing this video now (1 year later). It's amazing how much things improve when we find out how little we know about our system and then work to get the most out of it. Like Gene already mentioned, proper multi sub placement is key to getting better bass. Hindsight being 20/20...Looking back at your other setups (before the JTR subs), if you had taken the time to learn REW and the Mini DSP the same way that you did now, you could have gotten very similar results with your other subs. I'm sure the JTR have more output, but as far as the response goes, (since most of that is room and placement dependant) with proper tuning you could have had similar results. In my own room (today), I have 4 SB-2000 Pros tuned via REW, MSO, and MiniDSP. My bass response is flat from around 10Hz to 100Hz. It take lots of time and learning, or a good friend who knows how to work with it all, but it's possible. I'm sure that today your bass response is even better and hopefully the same across all seats (like Gene was alluding to in his comment).

Thanks; even before moving the sub-woofers and taking measurements of the room's response I would recommend using the feature in REW that models the frequency nodes. One just enters the dimensions of the room, the positions of the speakers and the listener and it graphs the response in the room before lifting anything

[DerekBove]

Great video! I just actually used my MiniDSP for the first time this weekend. I think the reason for the slope is our ears have a harder time hearing <30 hz so higher output in the low end, sloping downward is preferred. I also found that YPAO did a really good job of aligning my subs.

[gibluap]

From what I understand the house curve sloped upward as you get lower in Hertz is good cuz you don't want to lose output on some of that serious, chest-pounding, impactful bass. A lot of times guys will have what they think are bad subs and you run a sweep on them and you see that they're almost running a flat line of dipped line. The house curve will increase the output at the lower decibel and the bass response is just better.

Home Theater Gurus videos are amazing!!! He really does know his stuff and breaks it down so most can understand. Amazing and unbelievable what he did with your subs!!! He needs to start offering remote room EQing.

[blswagger]

Congrats on getting such great results! I plan on giving REW and a miniDSP 2x4 HD a shot once my dual Rhythmik F18s come in. The whole process seems very complicated and daunting and I don't have a friend like Tony to help me out. I'll watch as many YouTube videos on the subject and check out the forums for help. Thanks for posting this to show it's worth the effort!

[sherazdotnet]

I have never commented on our channel but there are few things that need to b pointed out.
First, Your raw (non EQ) response starts at 10Hz and your EQ response goes way below it. No EQ can achieve this. Clearly, you took before reading in REW starting from 10Hz and after EQ starting from 0. Please mention this in your video otherwise this can mislead others.
2 - I believe both of your subs are placed at the front of room b/w your L/C/R speakers? If that's correct then most likely you shouldn't have to add any delay. Adding 12ms of delay to align their response shows that you have polarity inverted in 1 of your sub. Take each sub reading without any EQ and turn acoustic timing reference on and then see in impulse response under Overlay window if their peaks are in same direction. Most likely they are in opposite directions which indicates that 1 of your sub is inverted.
3 - Your initial FR shows major room issues where you have your subs placed. I'd recommend you to move one of our sub to the back of your room. Most likely you'll get quiet the opposite response in the back of your room where you are going to gain all this midbass that you are missing in the front. Then after setting delays of both subs, you are going to get a very flat response without any EQ.
4 - When taking raw response, don't setup your subs to be crossed over at 120, Go as high as you can. I can explain why later if you need to know.
4 - Finally, the final FR you have that SAWK setup is called a House Curve. If you notice, 100Hz is almost 10dB lowered. That's because 100Hz sounds a lot louder than 70Hz and 70Hz sounds louder than 30Hz. In other workds, assuming you have flat response with any dips/peaks, play a 100Hz tone and see on spl what it reads. Then play 30Hz. You'll see that 30Hz will come a lot less than 100Hz. In order to compensate this, we use house curve where low end is ~10dB louder than high end.

Happy for you that you got to experience what minidsp can do for your bass!

I use it as well and can get a similar curve in my room with 4 svs sb12-nsd subs, although in my room they only extend to about 16hz -3db because of roomgain.

Next up would be to learn understanding waterfall, IR, delay and phase plots to try and get 'the best' integration with your mains.

About your initial left and right summed subs plot, being that you lost so much output at those low frequencies (long wavelengths), it almost looks to me that your subs were 180 degrees out of phase. Of course i don't know your exact room size and equipment setup, but might be something to look in to if you ever decide to do it all over.

Enjoy your smooth bass sir! I know what a gamechanger it can be!

[TheWizardofMNT]

Home theater guru's videos also helped me figure out how to use the minidsp and is one of the reasons I got one! A great resource to learn from. I'm still learning audio and going down the rabbit hole. Thanks for the video!

[burningsti]

I hope all your filters are on the output so you can take advantage of BEQ on the input side ! If your mind is blown now, wait until you can take
advantage of that extension on every movie that’s out. The miniDSP + BEQ is the best investment to a home a theater period.

[Audioholics]

Nice video as usual man. Those nasty wide suckouts you measured for each sub are likely more to due with the cavity you placed those subs in. It's always a good idea to optimize placement and time/phase alignment Before engaging ANY EQ at all.

You can't use EQ to fix seat-seat variance. You can flatten common bumps across ALL of your seats IF you first fix seat-seat variance with proper multi-sub placement. You only show measurements in one seat location so it would be interesting to see how this set up affected other seats.

The massive 30dB suckout at very low F was odd since your subs are so closely spaced together and relatively the same distance from your seat. Were you using the same sub out of your processor when connecting each sub or did you have independent sub outs and just forget to adjust the delay on one of them? It's possible one of the subs was simply out of phase and you fixed it by adding delay once you added the mDSP box. The rising bass with lower F is part of the goal of developing a room curve for better sound and varies depending on the room size and speakers utilized.

Great video Youthman! I started researching MiniDSP's a couple days ago. Great timing with your video release! You nailed it when you said it's overwhelming without good video instruction. Man, are there a lot of settings and variables and there is no one around to help answer questions. But you linked up you pal's video dissertation on the config/setup of REW so I'm gonna watch that next in my quarantined state of Colorado. Thanks Youth!

[Gshiznit]

Thanks for bringing back that famous catch phrase 👍 what a transformation your system just had.. wow. 😊

[cigarobsession]

The best bass test on a star is born is the opening scene. If it’s setup right, those drums will sound real. and yep, that 1917 scene literally made me jump out of my seat no joke
